At home I planted a thick blue gum pole deep in the ground near the mango tree out front, then made my own hammock out of knotted maize sacks. For the next three weeks, I began a rigorous course in independent study, visiting the library in the mornings, and spending the afternoons reading in the shade.
Gilbert offered to help right away. Each day I met him after school and he told me what they'd done in school.

Explanation:

cat is right with a just the answer is He is determined and hard working

The answer is A on Edge2021

Explanation:

I began a rigorous course in independent study.

the correct answer is video games and fast food.

hope this (:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
